EMC mess sends New Zealand University TITSUP for two days

Is it possible to build this type of redundancy/fail over when systems get this large? If so, is the time taken to switch between the two quick enough to minimise downtime to an acceptable level at a cost which is affordable?

This isn't meant to be knocking DR plans/redundancy/fault tolerance, more a question that as systems get bigger and storage more complicated is it affordable to split resources over multiple vendors to stop instances like this? It'll be interesting to see what the RCA is for this fault, if it was a EMC failure exacerbated by other faults or just a single failure somewhere which took out a lot more.
